Example Embodiment

[0019] The present invention will be further described below with reference to the drawings and embodiments.
[0020] With reference to the drawings, this embodiment includes a load-bearing rotating shaft 1, a rotating shaft body fixing frame 2, a longitudinal sliding frame 3, a seat back fixing block 4, a vertical sliding frame 5 and a connecting pin 6; The shaft fixing frame 2 is connected, the load-bearing rotating shaft 1 is connected with the longitudinal sliding frame 3, the longitudinal sliding frame 3 is installed on the vertical sliding frame 5, and the vertical sliding frame 5 is connected to the seat through a connecting pin 6 The seat back fixing block 4 is connected.
[0021] In this embodiment, the load-bearing rotating shaft 1 includes a load-bearing rotating shaft body 1-1, a deep groove ball bearing 1-2, a slotted nut 1-3, a top column 1-4 between the bearings, a tapered bearing 1-5, Spring washer 1-6, flat washer 1-7, rotating screw 1-8; the deep groove ball bearing 1-2 and the tapered bearing 1-5 are assembled in two bearing positions of the load-bearing rotating shaft body 1-1, The middle is supported by the top post 1-4 between the bearings, and the rotating screw 1-8 passes through the middle of the load-bearing rotating shaft body 1-1 via the flat washer 1-7 to connect with the spring washer 1-6 and the slotted nut 1-3 .
[0022] In this embodiment, the longitudinal sliding frame 3 includes a longitudinal sliding bearing 3-1 and a longitudinal sliding bearing fixing frame 3-2, and the longitudinal sliding bearing 3-1 is installed in the longitudinal sliding bearing fixing frame 3-2.
[0023] In this embodiment, the up and down sliding frame 5 is provided with an up and down sliding groove 5-1 and a rotating fixing screw hole 5-2.
[0024] Use: Load-bearing rotating shaft body 1-1 is welded to the center hole of the rotating shaft body fixing frame 2, the four nuts of the base of the rotating shaft body fixing frame 2 are locked and fixed with the external fixed point, deep groove ball bearing 1-2 and cone type Bearings 1-5 are mounted on the two bearing positions of the load-bearing rotating shaft body 1-1, the middle is supported by the top post 1-4 between the bearings, and the rotating screw 1-8 plus the flat pad 1-7 are used to rotate the fixed screw hole 5-2 is fixed with tapered bearing 1-5, so that the vertical sliding frame 5 can be rotated 360 degrees. The four longitudinal sliding bearings 3-1 are fixed by the longitudinal sliding bearing fixing frame 3-2, which can slide up and down in the upper and lower sliding grooves 5-1. The longitudinal sliding bearing fixing frame 3-2 is connected with the seat back longitudinal fixing frame. They are connected by a connecting pin 6, so that the seat back fixing block 4 can make a certain tilting movement, and the seat back fixing block is locked with the seat back. The seat can move up and down, forward and backward, and rotate.
[0025] The present invention utilizes a free-moving mechanical method, which can bear pressure in one direction and can also move in multiple directions freely. After the seat is installed, the angle of the side fixed with the machine can be changed. When it does not affect the level of the seat, the seat can use the downward gravity to keep the seat always in a vertical downward direction.
